The Inductance-Capacitance (LC) meter is an electronic instrument that can be used for the measurement of the value of unknown inductor or capacitor of a simple coil. This paper aims to discuss the concept and the technique of measuring the unknown inductance and capacitance with the help of a microcontroller board. This meter makes use of the resonance frequency of a tank circuit which consists of a capacitor and an inductor and an unknown inductor or capacitor value connected in parallel. This changes the natural frequency at which the tank circuit resonates. The new frequency depends on the value of inductance or capacitance. The new frequency is determined and the value is calculated with the help of simple mathematical equations. AVR Microcontroller Board has been used to develop this instrument. It consists of an ATmega328p micro-controller chip that facilitates the operation.
